presidency. for a time last night, i was tweeting in live time, mr. vice-president, it was funny. at one point, i said, this isn't funny anymore. because it seemed uncontrolled, hyperactive, manic. and then i saw a drawments -- i don't know if you picked this up, not very many people in the media picked it up. but then his mood changed, sort of dour. is this part of a personality trait that you have seen before? you said you had seen some of this on display in the past? >> well, i have seen him in meetings, when we had congressional types down at the white house. he was a [inaudible] personality. people say, that's joe being joe. but, you know, i couldn't help but think last night, and his questions, why did obama pick him to be his vice-president? he campaigned against him in the '08 election. joe won every debate.
